Extended data:
Square root refers to a mathematical operation, the operation of finding the square root of a number is called square root, and the square root is the inverse operation of square.
The operation of finding the square root of a number is called square root, where a is called square root. A must be greater than or equal to zero in the real number range, that is, A is non-negative; In the range of complex numbers, the square of I is defined as-1, that is, the square root of-1 is +/-i, and I 2 =-1.
Calculator is an electronic machine invented by modern people that can perform digital operations.
Modern electronic calculator is a hand-held electronic machine that can perform mathematical operations. It has an integrated circuit chip, but its structure is much simpler than that of a computer. Can be said to be the first generation of electronic computers (computers), with weak functions, but more convenient and cheaper. It can be widely used in business transactions and is one of the necessary office supplies.
In addition to displaying the calculation results, there are often overflow instructions, error instructions and so on. The calculator is powered by an AC converter or a battery, which can be charged by an AC converter or a solar converter. In order to save electricity, calculators all use large-scale integrated circuits made by CMOS process.
Calculator is generally composed of arithmetic unit, controller, memory, keyboard, display, power supply and some optional peripheral devices and electronic accessories, and is composed of manual or mechanical equipment. The arithmetic unit and controller of low-level calculator realize simple serial operation through digital logic circuit, and its random access memory has only one or two units for accumulation storage.
High-end calculator consists of microprocessor and read-only memory, and has many random storage units to store input programs and data. The keyboard is the input part of the calculator, generally using contact or induction. In order to reduce the size of the calculator, a key often has multiple functions. The display is the output part of the calculator, including LED display or LCD display. In addition to displaying the calculation results, there are often overflow instructions, error instructions and so on.
The calculator is powered by an AC converter or a battery, which can be charged by an AC converter or a solar converter. In order to save electricity, the calculator is a large-scale integrated circuit (see complementary metal oxide semiconductor integrated circuit) made by CMOS process, which is equipped with an automatic power-off circuit and works irregularly. The peripheral equipment that the calculator can choose is a micro printer, a cassette player and a magnetic card player.
